Hold light on bongo cut out.

Jim the Box · Post by **Jim the Box** » Mon Feb 08, 2016 1:58 am

Had a call for advice from the lad I sold my bongo to, he had pulled over on the A1, as the hold light was on and the bongo had cut out, I explained to him the hold light shows the hold button has been depressed, usually to assist in negotiating hills be it up or down them, any ideas why the light is on and the engine cutting out. The light was permenatly on not flashing.

Does pressing the button put the light off, and does the engine start again?

Yes it does Bob but after several miles it happened again, that's when he called me yesterday for advice, both times he started the bongo no problem after pressing and clearing the hold button. I've asked him to call me to let me know how things went, and any further issues whist making his way home, haven't heard from him yet but assume he got home ok, I hoping he is now looking for a bongo friendly garage in Edinburgh. But I was hoping the fault has occurred previously with someone on this site, typical, 4 years with only a slight misfire on LPG which a set of new leads cured, you sell it on and and it breaks down.

I wonder if he is pressing the button without realising (I still do it) and perhaps there's a short somewhere.

Does make you feel bad, thought.

No doubt our techie experts will have some ideas.

Possibly a problem with the speed sensor on the gearbox. Worth finding out if the speedo was still reading correctly when the light came on.

I've left a message for to him give me a call Simon to get all the symptoms, and if the fault is still occurring, I'm wondering if he has bad fuel due to running on LPG all the time and the petrol has got a bit waxy, and if he has hit the hold button in error the higher revs mean more demand for fuel causing it to possibly misfire or cutout.

Hi Jim,

Didn't get your message, was it email or phone? Did you get my text on Monday?

Until Sunday I'd been running only on petrol so not too sure it'll be a wax problem.

When I spoke to you on Sunday it had cut out twice in a short space of time. Both times the van seemed to shudder and then I lost all power both these times the "hold" light flashed but I didn't notice how many times.

Then I took your advice and sat at between 55-65mph from Gullane down to Durham, adding 50L of LPG en-route. In this 2.5hr period it only cut out once and that was through roadworks near Newcastle when I had to reduce speed to 20mph. I seem to recall this was just after I turned on the lights due to heavy (you could say lashing) rain.

After a 45mins stop in Durham I drove home again and had no further cut outs.

Having read the "Hold Light Flashing" factsheet a lot of it sounds familiar but in different combinations.

I reckon I've hit the hold button while doing 60mph on the motorway. I'm going to try and find an autobox specialist in the Edinburgh area to take a look and if not there is one recommended in Glasgow, Top Gear.

Thanks again for your help with this and sorry to interrupt your Sunday.

Hi Thriller

Welcome to Bongo Fury, sorry to hear you have a problem but you're in the right place and our techie experts will have some ideas I'm sure.

Not sure petrol will go 'Waxy', diesel can in cold weather, and petrol can loose volatility over time and go 'Off', but that doesn't sound like your problem.

Keep us up to date and help will be along.

My V6 is LPG .. I can't say that I have ever had any issues .. well apart from an initial lumpy tick over in cold weather when changing over to gas in slow moving traffic .. when fully warm or on a longer run no problems ..

I cured my 'initial' problem with new spark plugs .. dizzy cap .. leads and rotor ..

My way of looking at your problem would be to see when the problem comes on .. if it's running on LPG switch over to petrol .. if the problem disappears 'maybe' an issue with LPG ..

Or the exact opposite scenario .. if it's running on petrol then switch over to gas .. if the problem disappears 'maybe' an issue with the petrol system ..

Maybe something as simple as a blocked vent hole in the fuel filler cap ..

Hi Neil,
The gearbox specialist needs to be familiar with bongo fault codes, and it will probably have to be flashing when you take it to him, not sure if the flashing hold light is entirely relevant to the gearbox or if it details a fault elsewhere on the engine/electrical system, there should be a pattern to the flashes i.e. One long flash several shorter flashes, then it's a case of matching the fault code to the data sheet, bongos as far as I know can't be plugged in to a standard diagnostic machine.
They guys on this website will answer almost any questions you put to them so don't be afraid to ask, please give me a call (any evening) please let me know how it's progressing,

Jim

A quick search on here endorses your line of thinking, Jim. Many possible causes, electrical or transmission.

Such as this thread: http://www.igmaynard.co.uk/bongo/forum/ ... mp#p604003

Or maybe something in this search [hold AND light AND (limp OR flash OR flashing) NOT roof] resonates with this Bongo's scenario

Jim the Box · Post by **Jim the Box** » Wed Feb 10, 2016 7:15 pm

I would add a few gallon of petrol to the tank in case the petrol has gone off due to running on LPG, check the petrol cap hole is clear, check the transmission oil, it should not be a dirty dark red, and should not smell of burnt toast, run it on petrol, run it on LPG see how it performs, if the light does come on note the pulses to get the code, post your results on here, someone will advise what the code means, if the fault is not a simple fix and you are a bit reluctant to repair it yourself, then take it to a bongo friendly garage, or to campers Scotland who do a lot of work on bongos, or the garage at east Linton, I would not go to a gearbox specialist who does not know bongos, could cost you a fortune for nothing, as not all faults highlighted with a flashing hold button are gearbox related.
I would also start it up during darkness hrs and check its nothing simple like the coil or a HT lead arcing, don't know if a dodgy rotor arm or distributer cap would trigger a fault code on the hold button,
Sorry I can't be of more help Neil as I have never had to trace a flashing hold fault myself.

Yep seems to follow a similar pattern
Thanks for finding, may be of some help to Neil.

re the stall when you put your lights on.

to me it sounds like a basic lecky problem,engine earth strap, battery terminal loose, poss alternator or split charge side feeding back, get the alternator checked by a pro just to rule this out, the gearbox is really twitchy when the lecky supply is acting up, the hold light flashing also points to this, something is shorting /failing somewhere.

As the speedo got a MPH face overlay .. or is it chipped ..??
